Treatment of refractory symphysitis pubis with intravenous pamidronate.

Osteitis pubis is a noninfectious painful inflammatory disorder of the symphysis pubis. Etiologic factors include urologic procedures, abdomino-perineal and gynecological surgery, and spondyloarthropathies, although many cases are idiopathic. Most respond to conservative measures consisting primarily of rest and analgesic/antiinflammatory agents. We describe 3 cases, 2 with idiopathic osteitis pubis and one that was associated with a spondyloarthropathy, that failed to respond to conservative measures but experienced clinical remission with 3 to 6 monthly courses of intravenous pamidronate. Remission was also evident in 2 patients on isotope bone scan. Followup has revealed no recurrence. Intravenous pamidronate may constitute a safe and effective treatment option for patients with refractory osteitis pubis.
